The 25-06 Remington originally was a wildcat cartridge first introduced by A.O.Niedner in 1920 based on 30-06 Springfield brass necked down to .257" caliber, it was adopted by Remington and introduced to the shooting public in a Remington model 700 bolt action rifle in 1969. The 25-06 Remington is a true dual purpose cartridge, it can be used for varmints sending a 85 grain bullet out the muzzle at 3,500 feet per second, making this a very good, flat shooting varmint and predator round or it can be used as a big game cartridge sending 115 grain bullets out the muzzle at speeds of 3,100 feet per second for which it has sufficient power out to the 400 yard mark for thin skinned deer sized game animals.

The 25-06 Remington with the power it offers down range will also recoil somewhat to the shooters shoulder with heavier bullet loadings, however, bullets in the 100 grain weight range recoil is less and also works well for a nice combination load for deer, predators and varmints which is quite pleasant to shoot.

While much has been written about the 25-06 Remington cartridge, it truly is a great North American, dual purpose, varmint and big game cartridge.
